本文件收集了有关通常用于制造工业应用管道部件的热塑性材料在一定温度范围内对流体的综合耐化学性的可用数据。 本分类涵盖的基础热塑性材料有: 聚乙烯？PE 注1？本文件中考虑的PE对应于PE-HD，最小密度值为0,935？g/cm3（例如:PE63，PE80，PE100，PE100-RC，PE-RT）。 聚丙烯？PP（PP-R和PP-RCT、PP-H、PP-B） 聚氯乙烯，未增塑？PVC-U 氯化聚氯乙烯？聚氯乙烯-C 聚丁烯？铅 丙烯腈/丁二烯/苯乙烯？ABS 聚偏二氟乙烯？PVDF 注2？本文件考虑均聚物PVDF。 交联聚乙烯？-(-A,-B,-C) 乙烯三氟氯乙烯？ECTFE 聚酰胺，未增塑？PA-U(PA-U11,PA-U12) 注3？本文件仅关注PA-U11和PA-U12，因为这些长链PA-U根据ISO？16486-1;短链（例如PA 66）和增塑PA不用于整体塑料管道部件。 聚砜？PSU 全氟烷氧基？PFA 注4？在与原材料制造商进行评估后，可以应用高于200°C的温度。 聚四氟乙烯？聚四氟乙烯 注5？在与原材料制造商进行评估后，可以应用高于200°C的温度。 ？ ？ 聚苯硫醚？PPS 注6？PPS在工业应用和耐化学性问题方面是新的；因此，建议制造商和最终用户评估材料的化学适用性。

This document collects available data on combined chemical resistance of thermoplastic materials typically used to manufacture piping components for industrial applications, against fluids over a range of temperatures. The base thermoplastic materials covered by this classification are: Polyethylene？PE NOTE 1？The PE considered in this document corresponds to PE-HD, with a minimum density value of 0,935？g/cm³ (e.g.: PE63, PE80, PE100, PE100-RC, PE-RT). Polypropylene？PP (PP-R and PP-RCT, PP-H, PP-B) Polyvinyl chloride, unplasticized？PVC-U Polyvinyl chloride, chlorinated？PVC-C Polybutylene？PB Acrylonitrile/butadiene/styrene？ABS Polyvinylidene fluoride？PVDF NOTE 2？This document considers homopolymer PVDF. Cross-linked polyethylene？PE-X (PE-Xa, PE-Xb, PE-Xc) Ethylene chloro trifluoro ethylene？ECTFE Polyamide, unplasticized？PA-U (PA-U11, PA-U12) NOTE 3？This document focuses on PA-U11 and PA-U12 only, as these long chained PA-U are standardized according to ISO？16486-1; short chained (e.g. PA 66) and plasticized PAs are not used for monolithic plastic piping components. Polysulfone？PSU Perfluoralkoxy？PFA NOTE 4？Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. Polytetrafluoroethylene？PTFE NOTE 5？Temperatures higher than 200°C can be applied after an evaluation with the raw material manufacturer. ？ ？ Polyphenylene sulphide？PPS NOTE 6？PPS is new with regards to industrial application and chemical resistance issues; for this reason, manufacturers and end-users are advised to assess the chemical suitability of the material.
